any matted fibers (such as entangled fibers I of wool) are combed ortornasunder prior to being fed to the carding or like cylinder.

.Thefeeding rollers at present made use of (especially in connectionwith the feeding of woolor the like to the main cylinder) consist of twofeeding rollers having comparatively large teeth for pulling asunder andfeeding the wool or the'like to a third roller fwhich' transferssaichfiber to the main cylinder.

semi-cylindrical roller d (or this may be a The teeth of the two rollersfirst before mentioned are arranged to intersect each other so as tocarry out the functions well known,

:butin the employment of these devices it is often foundthat matted orentangled fibers arefed to the mainicylinder and are not properlytreated. The ,Object of my invention is to producerdevices and operatesame in such a manner as to obviate or practlcally matted fibers tothe.

avoid the feeding of main cylinder.

In order that mysaid invention may be readlly understood, I havehereunto -ap-.

tpended sheets of drawings illustrative thereof, to which by. lettersand figures reference is made in the following description Figure 1 is asectional side elevation show ing the niain cy'linde'r of a cardingengine or the main drum of a willoying machine or of a machine of asimilar character, with the feed rollers and my improved parts mountedrelatively thereto as hereinafter described.

Fig. 2 is an elevation of the parts shown by Fig. 1, with devices fortransmitting motion to the parts arranged in accordance with myinvention.

Fig. 3 is a plan of the parts shown by Fig. 2.

The framework for supporting the several parts which are illustrated bythe drawings, is omitted for the reason that such frame- Specifieationof Letters Patent Q Patented 1H3, Application filed May. 13,1919. SerialNo. 296,760.

work may vary according to the particular type or class of machine or.to the particular design of any respectlve producer of said machine, assa1d framework forms no part of my .invention.

A indicates the first cylinder or first licker in, of a carding engineor the main drum of a like machine employed for similar purposes. I

To attain the object of my invention I make use of the usual pair offeed rollersa and b which have comparatively coarse or large teeth 2, 3,so that the fibrous substances may be fed thereto as by the travelingapron 0 in inannerwell known, the feeding actions 7O of said brattice cand the two rollers a and Z) are carried out by the motions of samebeing in the direction indicated by the arcomplete'roller as shown byFig. 3, when such. is desired tobe changed so that on one part of .thesurface'being worn or damaged the other part or surface thereof may bebrought into use as is hereinafter explained) and this semi-cylindricalroller is mounted in proximity to the upper roller Z) 7 of the usualpair of feed rollers a and b asis the third roller heretofore employed.

The teeth of the semi cylindrieal roller (Z are of similar character tothose of the rollers a and Z) and are arranged to point in the directionillustrated by Figs. land 2- while the teeth'of' the rollers a and];also point in the respective directionsjindicated i by Fig 1.

I cause the semi-cylindrical roller rlto' oscillate about its shaft '7by having a pinion 6 fixed upon said shaft 7 This pinion is arranged togear with a quadrant f mounted loosely upon the shaft 9 so-that itshorizontal arm f may be connected by a rod 9 to a crank it arranged torotate upon its shaft is as driven by the chain wheel m shown by Figs. 2and 3. Or the oscillatory motions of the semi-cylindrical roller d maybe effected or secured by any other well known mechanical devicesderiving their motion from any motor'part of the machine to which myinvention is applied,

and which arrangement will be well understood by those having aknowledge of this character of mechanism.

The arrangement of sprocket wheel m and its chain a as shown by Figs. 2and 3 is only to show one device that might advantageously be employed,and which might be brought to be situated in appropriate proximity tothe semi-cylindrical roller to which I desire to transmit oscillatorymotion.

The semi-cylindrical roller d has teeth 8 made to mesh orintersect withthe teeth of the roller 6 and the oscillations of the semi-cylindricalroller d are arranged to be derived from such motor part of the machineas will enable its oscillatory movements to be at a comparatively highspeed that is to say, whereas the rotary motions of the two feed rollersa and b may be about or approximately four revolutions perminute theoscillations of the semicylindrical roller are to be approximately onehundred per minute, thus no matted fibers carried through the feedrollers a and b can pass in their said matted condition beyond theoscillating surface or teeth8 of the roller d for the reason that thesaid teeth 8 of the semi-cylindrical roller (5 will tear or detach suchfibers from the upper feed roller 6 and in such direction as to carrythe detached fibers, toward so as to be fed to the first cylinder A ofthe machine, which cylinder A takes said fibers and carries them forwardin Well known manner. The advancing of the teeth 8 of the semi-cylin--drical roller, as described effects the feeding of the fibers to themain cylinder 0; while the receding motions of said teeth 8 have beenfound to have the effect of clearing the teeth 3 of the feed roller 6,hence in addition to the prevention of matted fibers being fed to themain cylinder A the apparatus-described also prevents any accumulationof same on the feed rollers in connection with which it is used.

As is hereinbefore stated, instead of the semi-cylindrical roller (Zbeing made use of, I may use a roller arranged so that when the teeth ofone section thereof are worn or become damaged then another section orportion of the periphery of said roller may be brought into use so thatthe teeth extending therefrom will carry out the functions desired. I e

The space or path through which the oscillations of the periphery of theroller (1 is or may be carried out at each oscillation is preferablyabout one third the circumfer-e opposite direction to that. in whichthey rotate, adjustable bearings for said rollers to enable the teeth oftl-iese-latter to be situated to operate close to the teeth of the Vcarding cylinder, a semi-cylindrical roller having teeth bent in anopposite d rectlon to the teeth of the feed roller to which itisadjacent, said teeth of the'semi-cylindrical roller engaging with theteeth of said feed roller, and means whereby oscillatory motion istransmitted to the semi-cylindrical roller.

2. In a carding engine or like machine, a carding cylinder having itsteeth bent in the direction in which it rotates, a pair of feed rollers,one of said feed rollers having its teeth adjacent to the teeth of thecarding cylinderand bent to point in the same direction as said teeth ofthe carding cylinder, a second feed roller having its teeth en gagingwith the teeth of the first feed roller and pointing in the samedirection at the point of engagement, a semi-cylindrical roller havingits teeth engaging with those of the second feed roller'and bent in thesame direction as the teeth of the carding cylinder, but not inengagement with said teeth of the carding cylinder, and devices fortransmitting oscillatory motion to said semi-cylindrical roller.
